BS 1873 Cast Steel Globe Valve
- 双恒
- China
Main features: Globe valve is a kind of valve that the flow pressure will be against the valve seal, so valve has to be compulsively closed until the valve have sealed tightly. When valve is opening, the flow rate can reach maximum when disc is opened to 25% to 30% of its nominal diameter. Globe valve has very reliable cutoff function, as well as disc stroke is in direct proportion with seat port opening area, which is very good for flow throttling. The valves can be used for control of air, water, steam and other corrosive flows.
